Not Find Installable ISAM" Exception When Trying To Read DBASE IV File?
Aug 27, 2010
I need to open and read a Dbase file in my ASP.NET application. When I try to open the connection, I am getting the exception "Could not find installable ISAM." I have tried the solutions in the top answer in this question, but they did not work for me.The filepath of the data file is C:devDATA.DBF. Here is the code I am using to try to open the connection:
Dim connectionString = "Provider=Microsoft.Jet.OLEDB.4.0;DataSource=C:devDATA.DBF;Extended Properties=dBASE IV;"
Dim connection As OleDbConnection = New OleDbConnection(connectionString)

I get this exception "could not find installable isam" when trying to read from an excel file in vb. I tried google and the most I get refers to a problem with my connection but I don't know how to fix that. Here is my connection string
Dim MyConnection As System.Data.OleDb.OleDbConnection
MyConnection = New System.Data.OleDb.OleDbConnection _
("Provider=Microsoft.Jet.Oledb.4.0; Data Source='" & Application.StartupPath & "kk.xls'; Extended Properties=Excel 9.0;")

Dim databasepassword

The error I am encountering occurs at the second con.Open() when I try to connect to a .mdb database file which I created in access, the function correctly tells me I have a password, but then once I enter my password I get the error defined in the title, and I have no idea why.

I'm using vb.net 2003 and I want to read excel file 2003 using OleDb Connection. But I have a problem when I'm putting the IMEX=1 property on the connection String. But when I have to romove this IMEX property, the system run without an error. Here is my connection string
xlsCon = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & pathName & " ; Extended Properties=Excel 8.0;IMEX=1")
I need to put IMEX property so that it tells the driver to always read intermixed (string, integer, date) data type on each cell.
Here is the error I've encountered.

I keep getting a "Cannot find installable ISAM" error in my catch. And I've set up my connection string the same way that is in my signature "Let the user select the connection string." Here is the connection string being used(I did MsgBox(con.connectionstring)
Provider=Microsoft.Jet.OLEDB.4.0;Data Source =C:Documents and SettingsPC #6My DocumentsVisual Studio 2010Projectsfajsdl;kfajsdl;klogin.mdb;Persist Security Info=False
Even if I hardcode the connection string, rather than using Dim con as New OledbConnection(My.Settings.login). I still get the ISAM error.

In VB.NET or C#, I'm trying to read the contents of a text file that is in use by another program (that's the point, actually, I can't stop the program or it stops writing to the text file, and I want to periodically read out what is currently in the text file in another program)[code]in VB the code is above (a C# answer would be fine as well), however, it still throws the IO exception "The process cannot access the file 'file.txt' because it is being used by another process." Are there any workarounds in this scenario?

How would I go about reading a textfile, finding values and using the values in the program?Now I want the program to read the text file, find [1], use the first line after [1] as value for a variable, and the second line as value for another variable. After that I will run some code with the values and then do the same thing again for [2] etc.

I'm scanning using WIA. What is happening is there is a temp file created under "C:Documents and SettingsuserLocal SettingsTemp". For some reason, the WIA service is deleting the temp file before I can transfer the image. The exact error is: "The system cannot find the file specified. (Exception from HRESULT: 0x80070002)". Is this a bug in WIA? The error occurs on the last line...

i want to ask about read file and then convert to binary i am using this code
Function readd(ByVal path As String, Optional ByVal Separator As String = " ")

Dim line As String
[code].....
it works fine to read small file, example 2MB file, etc but it get error "Exception of type 'System.OutOfMemoryException' was thrown." when try to read 100MB file i think the error code because the file is too big
For Each Character As Byte In ASCIIEncoding.ASCII.GetBytes(line)
oReturn.Append(Convert.ToString(Character, 2).PadLeft(8, "0"))
oReturn.Append(Separator)
Next
how can i read 100MB or bigger file?or maybe is it another method / code to read a file and convert it into binary?

I have a tool which reads dBase files and uploads the contents to SQL Server, part of a system to import shapefiles. It works but now we have a requirement to import files that include non-English characters (Norwegian in this case, could be other languages later) and they're being corrupted. The dBase files are being read using an OleDbDataAdapter. Stepping through the code I can see that the text is wrong as it is read in. I'm assuming it's something to do with code pages or Unicode but I have no idea how to fix it.A dBase Reader application tells me the DBFs are in code page 1252 - I don't know if this is correct. My upload tool runs on Win7 with English (UK) regional settings.[code]Is there a way to tell OleDbDataAdapter what code page to use or a better way to read dBase files from VB.Net?

I am attempting to modify DBaseIV files using ADO in .NET I am able to open and read the data with no problem but everything is showing as read only and there is no way (at least that I can find) to perform Updates/Inserts/Deletes to the underlying Database table.
There seems to be almost no documentation that I have been able to find dealing with DBASE files. I have found a few references that BDE (Bordland Database Engine) needs to be installed and used for changing DBASE database files. However, it appears that BDE must be purchased. I found one reference that indicated ADO Jet 3.5 would work but 4.0 would not. Then I found another that said 4.0 had been updated to include Update/Insert/delete SQL interfaces.
Can anyone point me in the right direction for being able to modify a DBASE IV database table using ADO (or some other method within .NET) It is currently not possible to change from DBASE to another database structure this may be coming in the next year or so but will still need to perform modification to DBASE files for the forseable future.

I've used visual basic in office before, but when it comes to writing applications in Visual Studio, my knowledge is fairly limited. I'm unsure on how to set up a connection in my application to connect with a dBase IV database that uses indexes (not sure if it matters if it has indexes or not). I will need to both read and write to this database.
